In Australia, the death toll from flood crisis in the south-east state of Queensland has risen to 10, as Brisbane and Ipswich prepare for unprecedented flooding over the next two days. Both cities are on flood alert, with heavy rain, releases from the giant Wivenhoe Dam and high tides set to combine to cause major flood peaks. The number of missing people has been revised upwards to 78, and there are serious concerns for 18 of those people. Authorities say thousands of properties could be flooded as the Bremer and Brisbane rivers hit record levels over the next two days. The Brisbane River is set rise to 4.5 metres tomorrow and could go higher than the 1974 floods that reached 5.45 metres. The Bremer River at Ipswich is now expected to reach 22 metres tomorrow morning – 1.5 metres above the 1974 levels. Large parts of Brisbane are already affected by flooding. A steady stream of debris is floating down the swollen Brisbane River, including boats ripped from their moorings by the force of the current, and a whole ferry pontoon. Queensland Premier Anna Bligh says the scale of the looming disaster is constantly being reassessed. Ms Bligh has urged people not to panic.
